- I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases
How do you use Sentry?

Which package are you using?
@sentry/vue
SDK Version

Framework Version
vue 3.2.45
Link to Sentry event
No response
Steps to Reproduce
- reload page
- find page load event
- the lcp fp fcp measurements are smaller than performance API
It looks like this is deliberately designed this way.. but in my opinionin, performance API provide startTimestamp
meaning that from navigation Start to First Content Paint.
But normalizedValue ≈ FCP - new Date()
is smaller than FCP, and it will be affected by javascript load time, specially in weak network.
This is fatal for performance optimization scenarios.
Expected Result
we should report startTimestamp to measurement's fcp/lcp/fp value, because it actual value.
Actual Result
normalizedValue ≈ FCP - new Date()
